Independent guide and Distance Chord
II789 is a search name here without a confirmed commercial identity. This guide hosts its own Distance Chord game. It confirms no outside operator, affiliation, official domain, licence, payment service or app. Similar naming does not establish a shared publisher.

Independent enumeration checks this demo
An independent oracle checks every one of the 65,536 binary 4×4 boards for hazard count and the pair-distance rule. It compares every tested conditional support and selected-cell probability with the actual game source. At least one million actual-source rounds are simulated per mode.
This supports Distance Chord mathematics only. It is not an outside RNG certificate, operator licence, app safety guarantee, payment verification or local legal permission. A logo, HTTPS connection, matching hash or publisher label alone does not establish an outside service.
Distance Chord needs no APK
This game runs directly in the browser. The guide supplies no verified II789 APK, package identifier, publisher signature, release number or store link. APK search wording is not proof of an application’s existence or identity.
No unknown-source permission, protection bypass, installation or device access is needed for this demo. A matching icon or version number does not establish a file’s safety. This game’s probabilities cannot validate external software.
The sum of all hazard-pair distances
Choose 3, 4 or 5 hazards on the 4×4 board. Rows and columns are indexed 0–3. Distance between two cells is the absolute row difference plus the absolute column difference.
Count every unordered hazard pair once. The sum of all these distances must be divisible by three; individual pairs need not be divisible by three. Legal supports contain 188 layouts for three hazards, 469 for four and 1,444 for five. A layout is sampled uniformly once at the start and stays fixed. One captured stake covers the whole round.

How are hazard-pair distances combined?
Choose 3, 4 or 5 hazards on the 4×4 board. Rows and columns are indexed 0–3. Distance between two cells is the absolute row difference plus the absolute column difference. Count every unordered hazard pair once. The sum of all these distances must be divisible by three; individual pairs need not be divisible by three. Legal supports contain 188 layouts for three hazards, 469 for four and 1,444 for five. A layout is sampled uniformly once at the start and stays fixed. One captured stake covers the whole round.
How is the selected cell priced?
After the opened safe cells are known, let N be the number of legal layouts consistent with that history. For an unopened cell let K be the number of those layouts where it is safe. Its safe probability is K/N. Each eligible cell shows that probability; it is not a generic remaining-safe-cells ratio. The quote starts at 0.97. A safe reveal changes quote q to q×N/K, using the probability of that very chosen cell before revealing it. A hazard ends the round with zero return. Collect returns captured stake times quote, with fractional carry. The identity (K/N)×(q×N/K)=q explains 97% expected gross return for choices using revealed information. This is not a win probability or a guaranteed session return.
